MEASURING, AND DELIVERING MOLTEN GLASS.

Patented Jan. 16, 1906.

Application filed February 16,1904. Serial No. 193,773.-

To all whom, zit mcty cncern- Be it known that I, WALTER D. MORRISON, a citizen, of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements inMacl'iines for Automatically Segregating, Measuring, and Delivering Molten Glass, of which the following is a specification:

My invention relates to improvements in apparatus for manufacturing glass articles,

V and pertains articularly to means-for segregating a pre etermined quantity of molten lass from the melting- 0t and delivering it in plastic condition to t e molds. Its object is to provide a practical and simple machine which will automatically do the work of the skilled workmen known as the gatherer' and f presser now employed, the one to gather the glass through an aperture in the melting-pot upon a pontil or, punty and transfer it to a mold in the press where the other severs, by -means of a pair of shears, the estimated quantity re uired. The invention consists o the parts and the construction and combination of parts hereinafter more fully described, having reference to the accompanying drawings, in which- Figurel is a side elevation of my a paratus, partly in section. Fig. 2 is a rent view 0 same, partly in section. Fig. 3 is a plan view of the revoluble table. I A represents a melting-pot ofany suitable size, sha e, or construction, and 2 is a comparative y small chamber communicating with the potthrough an aperture controlled by the gate 3. The material in chamber 2 is maintained in the same heated and plastic condition asthat in pot A, and discharge to my a paratus and to the molds is from this chain er. This apparatus com rises a horizontal intermittently ifevolub e table 4, mounted on shaft 5, driven from any suitable source of power and provided-with a series of radially-disposed pockets .6. This table is arranged in suitable relation to chamber 2, whereby the pockets are adapted tore ister with an opening 7 in the bottom of the 0 mmber at each successive movement of the table. These pockets are presumed to contain each i'ust the desired amount ofymaterial for a jar, ottle, or thedike of a particular size. The pockets 6 are preferabl o n at top and bottom and referably in t e fii rm of a truncated cone wit the lower discharge end larger to expedite delivery of the'heavy viscid contents.

Between the under side of chamber 2 and perforated correspondin ly with opening 7 is a hollow water-jacketed late 7, having a lower cutting edge 7", wit which the upper surface of table 4 has a snug sliding fit, the

two parts cooperating after the manner of a shde-valve to control the flow from orifice 7,

since discharge from chamber 2 is intended to'take lace only when a pocket is in line with or' ice 7. As a pocket approaches opening 7 the bottom ofthe pocket rides upon a ho low spring pressed segmental closureplate 8. Thelatter is inclined downward at the approach end, as shown at 9, and extends from a point beneath discharge-opening 7 to a point immediately above a mold 10 of a press. The length of the closure-plate is approximately e ual to the length ofone step movement of t e table. "The late 8 is so ported from a fixed part and is normal y pressed upward into the path of a pocket by the springs 11. Water is admitted to the chamber in plate 8 just as it is to plate 7, as

that the metal parts do not beglassto adhere to it is essenti come so hot as tocause the them.

The table is given a stepby-step, movement by any suitable means. In the present instance I have shown the'shaft 5 as having a bevel-gear 12 engaging a mutilated gear 13 on drive-shaft 14, so thatwith each revolution of the latter the table is moved to bring the pockets successively beneath opening 7 and over mold 10. The interval between each movement is onl Y long enough to allow one pocket, to fill 'whi e another is dischargmg.

. A plunger 15, is rcciprocable in line with opening 7in chamber 2 and coordinately with the intermittent movement of the table to assist the more rapid filling of the pockets, since the molten glass is comparatively sluggish in I its flow. As here shown, the opening7 is designed to hold more than is required to fill a pocket. The plunger has a movement from slot 17of the plunger-rod 18. Preferably ,design and arrangement of the parts being such that as the table is moving the plunger is retracted upward above the mouth of opening 7 to allow the latter to fill, the top of the table serving as a temporary closure. As soon as the table stops with a pocket between plates 8 and 7 and in line with opening 7 the plunger makes a rapid descent, forcing a quantity of glass into and filling the pocket, the excess in opening 7 displaced b the plunger escaping, as before stated, bac into chamber 2. The plun er is preferably concaved on its bottom, and the pockets are provided with minute perforations 24 for the escape of air.

The size and number of the pockets may vary according to conditions, and it is ob vious that various changes in details of constructionof the apparatus maybe made without departing from the principle of my invention.

llaving thus described my invention, what I claim, and desire to secure by Letters Patout, is-

1'. In a glass measuring and delivering apparatus, the combination with a melting-pot, a chamber leading therefrom, and means controlling communication between the pot and chamber, said chamber having a deliveryopening, of a carrier rotatably mounted be:

neath said chamber and provided with pockets adapted to be successively alined with said opening, receptacles fitted to the table in line with the pockets, and means for accelerating the delivery of the molten glass to the receptacles.

2. In lass-working apparatus, the combination with a source of liquid glass, of a rotatable carrier, open-ended receptacles adapted to contain a predetermined gluantity of liquid glass said receptacles 'depen ing from the under side of the carrier and successively interposed in the course of liquid-supply, and a.
